When you're meriting in parties, these are much better than Wizard's. I never worry about resists on experience mobs anymore, so that's when these gloves come in handy. I usually do +MAB/MP in meriting parties now.

As posted before, I usually only use Wizard's on high resist mobs where I need the +ELE magic skill to stay on top.

Assuming you're not fighting something like Gods where you'll get a lot of resists, yeah. Elemental Magic Skill is pretty awesome when you are getting resisted. I'll get both and swap them out as needed.
